I am separating water into hydrogen and oxygen via electrolysis.
The electrolyte solution is sodium hydroxide (NaOH) in deionized water.
Electrodes are 99.96% pure nickel.
All gases and liquids are perfectly clear. Even after running for hours, the electrolyte solution is crystal clear and colorless.
However, the reaction seems to be emitting something that burns the nose and throat of everyone in the room.
Is that some sort of gas from a side reaction at one of the electrodes, or is it simply bits of NaOH being carried into the air by the splashing bubbles?
